The subject of this paper is the development of a functional prototype for a platform designed for tabletop role-playing games (TTRPGs), applying the rules and logic of system design. The elaboration of the idea will take place on a smart interactive table intended for multiple simultaneous users. The aim is to create the first platform for interactive boards intended for broad usage, facilitating the play of various TTRPG systems. Users will have access to all necessary game components through an adaptable graphical user interface. Within this paper, a competitive market analysis will be conducted, along with a description of the platform's user base. The discussion will focus on the design of a functional interactive interface that guides users through this type of game, setting standards for further development of interactive tabletop games on interactive surfaces. A portion of the work will delve into the methodology and philosophy of designing tabletop role-playing games. Attention will also be given to testing the visual aspects of the platform, as well as the design of the system and its distinctions from rival applications. The practical segment of the paper will showcase the designed components of the unique gaming platform across various developmental stages.
